FOUNTAIN-PEN.

Specification of Letters Patent. i

' Patented Mar. 5, 1918.

Application flied October 29, 1917. Serial No. 199,005.

To all whom it may concern:

Be it known that I, HANs PETER RAVN, a

I citizen of the United States of America, and

' turn spring with an elastic terminal abutment and spacing extension,and third, to supply a pivoted lever for depressing said resser-bar,said lever having special engag ing-lneans at it's free end.

These objects I, have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Fi ure 1 is an elevation of a fountain pen em odyingmy improvements, with the barrel and inkcontaining sac-k therein shownin longitudinal section, and the said sack uncompressed; Fig. 2 is alike view of said fountain pen with the ink-containing sack compressed,and Fig. 3 is a plan view of the presser-bar with its return springhingedly connected thereto.

Similar numerals of reference denote corresponding parts throughout theseveral views. 7

The fountain pen shown is ofthe wellknown type in which a closed endbarrel 1 contains a closed end elastic ink-containing sack 2. A flatresser-bar 3 is positionedlongitudinally upon said sack under a lon.-gitudiiial medial slot 8 in said barrel 1. The numeral 4 denotes alongitudinally directed staple fixed on the middle of the upper surfaceof said resser-bar, and the flat return spring 5 has one end'orificed at15, one limb of said staple being received through said orifice tohingedly and loosely connect that end of the return spring to thepresserbar to permit the spring to freely swing to and from theresser-bar without binding or exercising. any constraint upon thepresserbar while swinging.

The numeral 6 denotes a U-shap'ed flat spring havin one end fixedlysecured by means of smal rivets'14 to a place on said return spring 5removed a short distance from its free extremity, said extremity thusextending at 7 beyond the hook 6 for a uri 'pose to be described. TheU-shape or hooked spring member 6 has its free member passed under theclosed end of the inkcontaining sack 2 a short distance, but this is notessential. The numeral 9 denotes a lon itudinallytroughed lever mediallypivote on a intle 13 fixed across the slot 8 of said barre so that oneend of the lever may swing into the barrel to engage the middle part ofsaid presser-bar and compress the latter upon the "sack '2 to collapseand empty the latter.

The extension end 7 of the return-sprin 5, while the device is beingmanufactureif, can be suitably proportioned in length so as to insurethat when the presser-bar and spring 5 are pushed completely within thebarrel to have the extension 7 contact with the end wall of the barrel,the staple 4 will i be so located as to become a stop against which mayimpinge a small raised element 12 on the lower end of the lever 9 toprevent the latter from swinging in one direction bethe pintle 13, andthus making ,it easier and more convenient to thus start swinging thelever to the position shown in Fig. 2.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

Y 1. A fountain pen comprising a barrel, an ink-containing sack therein,a presser bar element for the sack, and a return spring element forthe-presser bar hinged thereto, said, spring having at its free end ahook, the extremity of the spring extending a'distance beyond the hookto engage the adjacent end wall of the barrel.

2. A fountain pen comprising a barrel, an ink-containing sack therein,a. Presser bar element for the sack, a return spring element for thepresser bar having one end hinged to an intermediate part thereof, saidhinge-connection comprising a staple on" the Presser bar and an orificein the return slotwith 'one end prewar-bar and having its movement thereover limited by engagement with said staple.

spring 'in which one limb of the staple is mounted loosely, said barrelcontaining a slot and a lever medially ivoted in said movab e againstsaid 3. A fountain pen eomprismg a barrel, an inkcontaining sacktherein, a resser-bar element for thesack. and a return s n-ing HANSPETER RAVN.
